I am shopping Petco.com right now for some silk plants to add to my tank. I did get some rocks from neighbor and I'm just not sure what they have been through. I'm thinking about order more rocks. I created this thread to ask if there is anything else that I should add to my order before I ship it out. Suggestions appreciated.

If you don't have a heater, I would definitely get one of those. The Hydor mini heaters work great.

If you're looking to upgrade your tanks, I highly suggest Petsmart. I don't know if its just where I live, but Petco's tanks are really expensive compared to Petsmart, especially if you're looking for one of the starter kits with extras such as filter, light, hood, etc. (If you already have all of that extra stuff, then their dollar per gallon sale is great!)

Last night I picked up a 5 gallon tank at Petsmart with a bunch of extras for $33. All I had to do was buy a heater, and I was still under what Petco charges for most of their similarly-sized setups. Walmart also has even cheaper set ups. (10 gallons for around $35 I think)

Okay. So far I put an order in for a 5 gallon tank. I also have black rocks and plants in my shopping cart.
But, I am thinking about a different product for black rocks instead of the glowrocks. I am worried that there is a funny texture to the black light sensitive rocks.

I'd get all the plants in all different sizes you can afford, bettas love them. A heater if you don't have one already, a sponge filter is nice because with a 5g you can definitely cycle (make sure you get all the parts though for a sponge filter, you'll need the filter, a small air pump, airline tubing, and a airstone to make it work, but still cheaper than a HOB, and several benefits to sponge filters as well)...that's all I can think of. :)

I make my own sponge filters because I've got tons of left-over bubblers from years ago, but I see the Hydro Sponge Filter Pro's recommended a lot. :)

Rocks are totally personal preference, like wallpaper, lol! :) I like the natural rocks just because they're neutral and I can get a big bag and use them in all my tanks, but that's just my opinion. :) If you like them, go for it! There's no wrong way to do it. :) And, if you decide you want all black later, it should be fairly simple to take the colored ones out. :)

Your plants are good, but you might want to consider the taller background plants of the same type. They're taller, so you get a little bit more "bang for your buck" in terms of cover. Since they're probably taller than your tank, or almost as tall, the background plants also provide you with more surface level cover since the plants will sag down at the tops, which is the level of cover bettas like the best and feel more secure with. :)
